Selection, using the cross breeds, has been made on the basis of the royal jelly productivity which is measured by the yield of royal jelly and per one queen cup as well as the larval acceptance in the period of nectar flow and non-nectar flow. Among them, cross breed B yielded 16.82g of royal jelly equivalent to increase of 46% and 29%, as compared to those of the control and cross breed A in the period of nectar flow, while yielded 19.37g of royal jelly corresponding to increase of 95% and 89%, as compared with the control and cross A in the period of non-nectar flow. The larval acceptance of the control was highest by 67.6% in the period of nectar flow, while that of cross B was highest by 86.0% in the period of non-nectar flow. The cross B yielded 0.34g of royal jelly per queen cup in the period of nectar flow and 0.39g in the period of non-nectar flow, which was increased by 61% and 50%, respectively as compared with the control. In conclusion, cross B yielded 18.16g of the total royal jelly and selected as the superior one in terms of the total royal jelly productivity.
